Abstract： 目的:探讨CCND1基因A870G多态与上海地区人群结直肠癌(colorectal cancer, CRC)遗传易感性的关系.方法:采用TaqMan MGB探针实时定量PCR法.检测104例CRC与205名对照人群CCND1A870G基因型分布及差异.结果:CRC组和对照组870A等位基因频率分别为60.1%和52.4%,A的CRC发病风险是G的1.40倍(95%CI=0.99-1.97,P=0.057).与GG基因型相比,GA基因型的CRC风险增加至1.99倍(95%CI=0.94-4.20,P=0.070),而AA基因型的CRC风险显著增加至2.46倍(95%CI=1.09-5.56,P=0.031).将GA、AA基因型合并计算,则其CRC发病风险与GG基因型相比呈相似的显著性增加(OR=2.13,95%CI=1.03-4.39,P=0.040).结论:CCND1 870A增加CRC发病风险,可作为这一地区CRC高危人群的筛选指标.
